The RGB display correct because they are RGB and looked right on your
monitor in the application they were created. CMYK images in PS are
displayed on screen by Photoshop as RGB representation of the file.
This RGB screen image is created internaly by PS by running the CMYK
back through the color conversion (CMYK-RGB) before sending it to
screen. (sort of a CMYK preview in reverse)
Be sure PM's color management is turned on and that you have selected
the correct profiles. When set up right it does a good job of
displaying most CMYK images. Be sure to set your inks to the proper
With the proper profiles and color management on, if you then export
to PDF you will be able to see a quite accurate soft proof of your PM
file. Great for finding problems before sending out for films.
For pages larger than 8.5 x11, select a postcript driver, set the
driver to 100% and Auto Tile, print the file to disk and then run
through Distiller at Print Quality. This PDF file can then be printed
on a lower end color inkjet with supprisingly accurate results. (this
process can create a extremely large Postscript file so be sure to
have plenty of spare space on your drive)
